Last week I received my Pentax K-x and I was able to shoot every old K and M mount lens I owned. I had to either use stepped down green button metering, or shot Av wide open, but a happy man was me!
Then a $25 Tamron 28-210 Auto KP/AR lens arrived, I removed the Ricoh pin, and now my K-x shoots that lens set on Auto with full connection for Program, Tv, Av, even the Scene modes. What a wonderful lens! All I do is focus and shoot!
Now I’ve won an FA 100-300 lens for $ 24.40 in an auction with four other bidders.
As I understand old Pentax lenses, a few FA lenses are still being made and they are full frame autofocus lenses that are current for the K-1 and work on all other modern Pentax APC DSLRs, including my K-x.
An FA isn’t optimized for digital, but why are they and other old Pentax lenses so cheap?
